Specification of Letters Patent.

Patented Sept. 18, 1917..

Application filed November 26, 1913. Serial No. 803,090.

To all whom it may concern:

Be it known that we, HENRY F. STOCK and JOSEPH NADER, citizens of the United States, residing at Waukesha, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification, reference being bad to the accompanying drawing, forming a part thereof.

This invention relates to bottle stoppers and the objects of the invention are to improve bottle stoppers in the manner to be specifically described and claimed.

A form of bottle stopper consisting of a metal cap adapted to be clamped to the neck of a bottle with a packing material to make a tight joint has come into common use and is a most desirable form of stopper where the contents of the bottle are not affected injuriously by the packing material. This packing material is usually a piece of cork or ground cork held together by some cementing material. Some mineral waters are very delicate and acquire the taste of cork or other available packing materials when bottled with such stoppers and other liquids are similarly affected if retained in the bottles for a considerable length of time. Unfortunately, materials which Will not affect the bottled liquids cannot be used for packing material to effect the desired results in any of the ordinary manners of utilizing such packing material.

This invention provides a bottle stopper which possesses all the advantages of the known construction and in addition provides for the sealing of the contents of a bottle in such a manner that the deleterious effect of the packing material is obviated.

Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of this invention, and on which draw ings the same reference characters are used to designate the same elements wherever they may appear in each of the several views, Figure 1 is a bottom plan view of a stopper, parts being broken away; Fig. 2 is a vertical section taken on the line a-a on Fig. 1, looking in the direction indicated by the arrows; and Fig. 3 is a vertical section through the neck of a bottle with the stopper applied thereto.

Referring specifically to the drawings the reference numeral 1 designates the metallic cap used with the form of stopper hereinbefore referred to and for further description of which reference may be had to United States Letters Patent, No. 468,258, granted February 2, 1892, to William Painter, of Baltimore, Maryland, for bottle-sealing device. The reference numeral 2 designates a thin metal disk which is large enough in diameter to extend over the mouth of the bottle. This disk should be thin enough to be bent or flexed when the stopper is applied to a bottle and can be made from any suitable material, but it is preferred to make it of pure block tin. A cushion 3 is inserted between the cap 1 and the disk 2 and an annular packing 4 is placed in the cap against the disk on the side thereof opposite the cushion 3. The cushion 3 may consist of cork, or other suitable material, the object of the cushion being to provide a resilient backing for the metal disk. The annular packing should have an internal diameter about equal to the diameter of the opening 5 in the neck of the bottle 6 and should be composed of some suitable substance Which will flow sufficiently to make afiuid-tight joint between the neck of the bottle and the disk 2. Paraflined paper is found to serve excellently for the annular packing 4 as the paraffin flows sufliciently to make a fluid and gas tight joint and this position without danger of displacement in assembling the parts of the stopper.

The stopper is applied to a bottle in the well-known manner and is removed therefrom in the well-known manner which require no further explanation but when the stopper is in use on a bottle the contents of the bottle cannot contact with the cushion 3 at all on account of the presence of the disk 2. Practically, the contents of the bottle can only contact with the glass of the bottle and the metal disk 2. Even ifthe contents of the bottle can contact with the packing 4 the area of the packing exposed to the contents of the bottle is limited to the thin inner edge of the annular packing which area is so small as to efl'ect no appreciable deterioration of the contents of the bottle.

What is claimed is: 1

The combination in a bottle stopper of an imperforate cap adapted to be secured to the neck of a bottle, a cushion in said cap and contacting therewith, a thin metal disk seated against said cushion on the side there of opposite said cap and extending substantially entirely over the interior of the cap and composed of pure block tin or its equivalent, and an annular packing of paraffined paper seated in said cap against said disk on the side thereof opposite the cushion, the Width of said annular packing being not substantially greater than the thickness of the necks of bottles With Which the bottle 15 stopper is to be used whereby the area of the p araffined paper exposed to the interior of the bottle Will be a minimum. 4

In Witness whereof We hereto affix our signatures in presence of tWo Witnesses.
